On March 13, 1974, a routine location shoot for a National Geographic history of Australopithecus turned into one of the most devastating losses in documentary filmmaking. A Sierra Pacific Airlines Corvair 440 carrying Wolper Productions personnel slammed into the White Mountains shortly after taking off from Eastern Sierra Regional Airport in Bishop, California. All 35 people on board were killed, including 31 members of Wolper's crew who had been dispatched to Mammoth Mountain Ski Area to film segments for what would be broadcast as part of the television series Primal Man. In a grim twist, some of the filmed segment was recovered in the wreckage and ultimately aired, but the human cost overshadowed any cinematic payoff. The crash was subject to investigation, yet the official cause remains unsolved, leaving families, colleagues, and Wolper himself to reckon with an unanswered tragedy that abruptly punctured the ambitious documentary expansion of the 1970s.
